rvilbert Posted September 25, 2020 Share Posted September 25, 2020 Good evening, I apologies for the broadcast message but i have decided to reinstall my Hackintosh machine using Catalina 10.15.6 and .... I'm stuck at "PCI configuration begin".. My configuration is: Asus X99 Deluxe Core i7 5960x 32 Gb memory GTX 980 Knowing that my graphic card would not be fully recognised in Catalina i have also tried to install High Sierra but I managed to get exactly to the same point and i have therefore decided to give another try to Catalina and .... I'm still stuck. (FYI I had managed to install 10.8 on my machine a while ago but a few things have changed since then and I may be missing a trick). In a nutshell I believe my issue is linked to this message that i'm getting: Waiting on <dict ID="0"><key>IOProviderClass</key><string ID="1">IOResources</string><key>IOResourcesMatch</key><string ID="2">boot-uuid-media</string></dict> I tried all options (with/without flags and with/without kext) but i think that my issue is between my DSDT, SSDT and config.plist files. Any help would be much appreciated! I have attached my EFI folder and the print screen with the error message. Let me know if you need any further information. Thanks a lot EFI.zip Link to comment https://www.insanelymac.com/forum/topic/345261-solved-help-for-catalina-10157-installation-on-asus-x99-deluxe/ Share on other sites More sharing options...
spakk Posted September 25, 2020 Share Posted September 25, 2020 add npci=0x2000 or npci=0x3000 to your boot flag and then it should work.

oliveg Posted July 17, 2025 Share Posted July 17, 2025 Dear rvilbert, Thank you for providing your EFI folder. I manage to buy the same set (Asus X99 Deluxe, i7 5960x) and to use your files too, except the SN of course. Is your EFI working the same under Big Sur, and did you try more recent versions? Thanks again! 🙂 Link to comment https://www.insanelymac.com/forum/topic/345261-solved-help-for-catalina-10157-installation-on-asus-x99-deluxe/#findComment-2837342 Share on other sites More sharing options...
